Reduces the overall costs of the state assessment system by implementing the eleventh grade English language arts and mathematics assessments being developed by a multistate consortium in which Washington is participating.

Maximizes use of the consortium assessments by developing a tenth grade high school English language arts assessment and modifying the algebra I and geometry end-of-course assessment to be used only during the transition to the consortium-developed assessments.

Reduces the number of assessments that will be required for students to graduate beginning with the class of 2019.

Provides that the eleventh grade consortium-developed assessments have two different student performance standards as follows: (1) One for the purposes of high school graduation that will be established by the state board of education; and (2) one that is intended to demonstrate a student's career and college readiness.
